Minnesota's harsh winters and freeze-thaw cycles are tough on roof flashing, the metal strips that seal joints. Moisture and road salt can accelerate corrosion, leading to leaks. We fix it by carefully removing the damaged flashing, preparing the underlying surface, and installing new, high-quality metal flashing sealed with durable, flexible sealants designed for our climate to ensure a watertight seal for years.

It depends on the cause. Often, leaks are due to failed seals or flashing around the skylight unit, which we can typically repair. We'll inspect the skylight curb, flashing integration with your shingles, and the glass sealant. If the unit itself is cracked or excessively aged, replacement with a modern, energy-efficient model better suited for Minneapolis weather might be the most reliable long-term solution.

Our thorough inspection focuses on vulnerable points. We examine all step flashing along walls and chimneys, valley metal, and vent pipe boots for corrosion or separation. For skylights, we check the perimeter flashing seal and the condition of the curb. We also assess the surrounding shingles and interior for water stains. This proactive check helps us catch small problems before they lead to major leaks or ice dam damage in your attic.
